Encrypt button disappearing from Outlook
Alex MelchingI found this issue to be due to licensing. after trying to troubleshoot why some of my users had the encrypt button in their outlook while others did not, a quick note from Microsoft confirmed what was an oversight. even though you can activate and enable OME for OWA for all users, to do so with those using local outlook client, they must have at least an E3 license assigned to them.
Note: Microsoft 365 Message Encryption is part of the Office 365 Enterprise E3 license. Additionally, the Encrypt-Only feature (the option under the Encrypt button) is only enabled for subscribers (Microsoft 365 Apps for enterprise users) that also use Exchange Online.
this note is under the section “Encrypt with Microsoft 365 Message Encryption"
Hello, that is absolutely not true. You do NOT need to have an Enterprise level license or subscription, but you do need supporting licenses and/or add-ons. When I started this post, that was the cause of the issue because after an update only Enterprise licensing (and O365 ProPlus) offered the Encrypt button and was quickly corrected when many SMB (with supporting licenses) users reported the issue as well. Supporting licenses: https://docs.microsoft.com/en-us/microsoft-365/compliance/ome-faq?view=o365-worldwide#what-subscriptions-do-i-need-to-use-the-new-ome-capabilities
Newer tenants also have certain OME and IRM settings already enabled where as older tenants that may have not used OME before do not have turned on and you should go through the OME and IRM settings and enable newer features if necessary. https://docs.microsoft.com/en-us/microsoft-365/compliance/manage-office-365-message-encryption?view=o365-worldwide
The page you reference does not have updated information.
- The page you reference doesn't say Enterprise E3 only. While not worded in the best way, it just says it's included.
"Microsoft 365 Message Encryption (Information Rights Management) - To use Microsoft 365 Message Encryption, the sender must have Microsoft 365 Message Encryption, which is included in the Office 365 Enterprise E3 license."
It's not just limited to Enterprise E3.
